Plastic rims are often referred to as plastic wheels or plastic hub wheels. In the context of carts, lawn mowers, or utility equipment, you might also see terms like deck wheels, spoked plastic wheels, or plastic caster wheels. These names can vary based on the specific use or design, but they generally describe wheels with a plastic core or hub, sometimes paired with a rubber or polyurethane tire for added durability and traction.

Yes, many wheels are made entirely from plastic, especially for light-duty applications.

• Plastic wheels are commonly used on lawn mowers, carts, air compressors, and some furniture.
• They can be solid plastic or have a plastic hub with a rubber or polyurethane tread.
• These wheels are valued for being lightweight, resistant to rust, and generally maintenance-free.

Cars don't use plastic wheels because plastic generally can't handle the high loads, speeds, and stresses that vehicles experience.

• Automotive wheels need to support significant weight and withstand impacts from the road.
• Plastic is more prone to deformation and damage under these conditions compared to metals like steel or aluminum.
• For safety and durability, car wheels are made from strong materials that can handle heat, friction, and heavy use.

Plastic wheels for carts, mowers, and similar equipment are typically produced using injection molding.

• Plastic pellets are melted and injected into a mold shaped like the wheel.
• Once cooled, the wheel is removed from the mold and may be fitted with a rubber or polyurethane tread for extra grip.
• Some wheels include ball bearings or metal inserts to improve performance and durability.

Choosing the right size plastic wheel depends on your equipment and its intended use.

• Check your owner's manual or the old wheel for size markings (diameter, width, and bore size).
• Consider the load capacity and the type of surface you'll be using the wheel on.
• Measure the axle diameter to ensure a proper fit.
